出于好奇,您在Java中可以拥有数组的多少个维度?
最佳答案
Java语言不限制维数,但是Java VM规范将维数限制为255。
例如,以下代码将无法编译:
class Main {
public static void main(String[] args) {
final int[][][][][][][][][][][][][][][][]
[][][][][][][][][][][][][][][][]
[][][][][][][][][][][][][][][][]
[][][][][][][][][][][][][][][][]
[][][][][][][][][][][][][][][][]
[][][][][][][][][][][][][][][][]
[][][][][][][][][][][][][][][][]
[][][][][][][][][][][][][][][][]
[][][][][][][][][][][][][][][][]
[][][][][][][][][][][][][][][][]
[][][][][][][][][][][][][][][][]
[][][][][][][][][][][][][][][][]
[][][][][][][][][][][][][][][][]
[][][][][][][][][][][][][][][][]
[][][][][][][][][][][][][][][][]
[][][][][][][][][][][][][][][][] x;
}
}
错误:
1.java:18: error: array type has too many dimensions
[][][][][][][][][][][][][][][][] x;
^
1 error
